[0025] To make the objectives, technical concepts and advantages of the present invention clearer, the technical concept of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Of course, the described embodiments are only a part, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative efforts based on the embodiments of the present invention are included within the protection scope of the present invention.

[0026] As shown in FIGS. 1 to 8, an embodiment of the present invention provides a lens module 10 including a frame mechanism 100 and an adjustment mechanism 200. The frame mechanism 100 includes a base structure 110, a support frame 120, and a lens barrel 130. The support frame 120 is suspended within the base structure 110. A movable cavity 1211 is provided inside the support frame 120. The lens barrel 130 is suspended within the movable cavity 1211. The adjustment mechanism 200 includes a magnet steel component 210, a shake correction component 220, and a focus component 230. The magnet steel component 210 is connected to the support frame 120 and at least a part thereof is provided to surround the movable cavity 1211. The shake correction component 220 includes a shake correction coil 221 and a shake correction reset member 222. The shake correction reset members 222 are respectively connected to the lens barrel 130 and the support frame 120. The shake correction coil 221 is connected to the lens barrel 130 and is used to drive the lens barrel 130 to move relative to the support frame 120. The focus component 230 includes a focus coil 231 and a focus reset member 232. The focus reset members 232 are respectively connected to the support frame 120 and the base structure 110. The focus coil 231 is connected to the base structure 110 and is used to drive the support frame 120 to move relative to the base structure 110. Here, the shake correction coil 221 and the focus coil 231 are respectively provided on opposite sides of the magnet steel component 210, and the focus coil 231 is located inside the movable cavity 1211.

[0027] In the lens module 10 of this embodiment, by installing the magnet steel component 210 to cooperate with both the shake correction component 220 and the focus component 230 simultaneously, the shake correction coil 221 and the focus coil 231 share a set of magnet steel components 210 to realize the optical shake correction and autofocus functions of the lens module 10, enabling the lens module 10 to have a more compact structure. Also, compared with the conventional lens module 10, by reducing the number of components, the mass of the movable member is reduced, effectively improving the accuracy and stability of the shake correction and focusing of the lens module 10, and enhancing the performance of the lens module 10.

[0028] Specifically, as shown in FIG. 3, the housing cavity 1111 is provided in the frame mechanism 100, the support frame 120 is suspended in the housing cavity 1111 of the base structure 110, the inside of the lens barrel 130 is used to mount the lens of the lens module 10, and the L in FIG. 1 is defined as the optical axis L of the lens barrel 130, and this optical axis L usually coincides with the optical axis of the lens in the lens barrel 130.

[0029] In this embodiment, the shake correction reset member 222 is electrically connected to the shake correction coil 221 and the support frame 120 respectively, and the focus reset member 232 is electrically connected to the focus coil 231 and the support frame 120 respectively.

[0030] Thereby, the shake correction component 220 and the focus component 230 are both electrically connected, and by being signal-connected to an external element via the focus circuit board 235 of the focus component 230, the signal transmission and power supply functions can be realized. Also, since the shake correction component 220 and the focus component 230 are electrically connected to the external element via the same circuit, the structure of the entire adjustment mechanism 200 can be made more compact. Therefore, the structure of the entire lens module 10 also becomes more compact, facilitating its arrangement in an electronic device.

[0031] In some embodiments, the shake correction component 220 includes two sets of shake correction coils 221, and is used to control the lens barrel 130 to move along the X direction and the Y direction perpendicular to the optical axis L to achieve the OIS shake correction effect. It can be driven to move the support frame 120 along the direction parallel to the optical axis L through the cooperation of the focus coil 231 and the magnet steel component 210. In this case, the two shake correction coils 221 and the focus coil 231 are connected in parallel to each other and conduct with an external circuit through four circuit contacts 2351 on the focus circuit board 235. Thereby, the OIS shake correction and the AF focus function can be realized simultaneously, and the circuit structure becomes more compact.

[0032] As shown in FIGS. 3 to 7, in one embodiment, the base structure 110 includes a base body 111 and a base insert 112, the support frame 120 includes a frame body 121 and a frame insert 122, the base insert 112 embedded in the base body 111 is connected to the shake correction reset member 222, and the frame insert 122 embedded in the frame body 121 is respectively connected to the shake correction reset member 222 and the focus reset member 232. By doing so, the circuit conduction between the shake correction component 220 and the focus component 230 is realized, and at the same time, the strength of the entire base structure 110 and the support frame 120 can be improved, and the structures of the base structure 110 and the support frame 120 can be made more compact. In other embodiments, the base structure 110 and the support frame 120 may realize the electrical connection function by means such as an external line, LDS technology (Laser Direct Structuring), etc., which are not limited here.

[0033] Specifically, as shown in FIGS. 5 and 6, the shake correction reset member 222 includes a flexible structure 2221 and a suspension wire 2222. The flexible structure 2221 is connected to the lens barrel 130. Opposite ends of the suspension wire 2222 are respectively connected to the flexible structure 2221 and the support frame 120. The suspension wire 2222 is provided outside the lens barrel 130 and is provided parallel to the optical axis L of the lens barrel 130.

[0034] By installing the flexible structure 2221 and the suspension wire 2222 to form the shake correction reset member 222, when the lens barrel 130 moves relative to the support frame 120 due to the drive of the shake correction coil 221, the flexible structure 2221 can be deformed to reset the lens barrel 130. By installing the suspension wire 2222 to be connected to the support frame 120, the structure of the shake correction reset member 222 and the support frame 120 can be made more compact, and the overall structure of the lens module 10 can be made compact.

[0035] In this embodiment, the shake correction component 220 further includes a shake correction circuit board 223. In order for the shake correction circuit board 223 to have a thinner thickness, the shake correction circuit board 223 is preferably an FPC. By electrically connecting the shake correction circuit board 223 to a plurality of shake correction reset members 222 respectively, the electrical connection function can be realized, and at the same time, a plurality of shake correction reset members 222 can be fixed.

[0036] As shown in FIG. 6, in one embodiment, the flexible structure 2221 includes a first fixing portion 22211, a first connecting portion 22212, and at least one first flexible arm 22213. Each of the first flexible arms 22213 is connected to the first fixing portion 22211 and the first connecting portion 22212. The first fixing portion 22211 is connected to the lens barrel 130, and the first connecting portion 22212 is suspended outside the first flexible arm 22213 and connected to the suspension wire 2222. When the number of the first flexible arms 22213 is plural, the plural first flexible arms 22213 are symmetrically provided from the suspension wire 2222, and each of the plural first flexible arms 22213 is connected to the first fixing portion 22211 and the first connecting portion 22212.

[0037] In this embodiment, the end of the suspension wire 2222 is welded and fixed to the first connection part 22212. To enhance the fixing firmness of both, it is preferable to cover a certain amount of solder on the connection part between the suspension wire 2222 and the first connection part 22212. When the lens barrel 130 moves relative to the support frame 120, the first flexible arm 22213 can be deformed to store elastic potential energy. After removing the driving force of the shake correction coil 221 / or when the elastic force of the first flexible arm 22213 overcomes the force caused by the vibration of the electronic device, the first flexible arm 22213 can serve the purpose of resetting the lens barrel 130 and achieve the shake correction function. When a plurality of first flexible arms 22213 are respectively connected to the first fixing part 22211 and the first connection part 22212, the elastic force of the first flexible arm 22213 can be improved, and the reset effect of the flexible structure 2221 can be enhanced. As shown in FIG. 6, in a preferred embodiment, in order to enhance the deformation range and reset effect of the first flexible arm 22213, the extending path of the first flexible arm 22213 is preferably a curved surrounding type structure. Specifically, the number of shake correction reset members 222 may be 2, 3, 4, or more than 4. A plurality of shake correction reset members 222 are uniformly provided along the circumferential direction of the lens barrel 130. By installing the plurality of shake correction reset members 222 to be connected to the lens barrel 130, the shake correction effect and reset stability of the shake correction component 220 can be enhanced.

[0038] In one embodiment, a relief hole 132 is formed in the outer wall of the lens barrel 130, and the relief hole 132 is provided surrounding the suspension wire 2222.

[0039] In addition, by installing the relief hole 132 to cooperate with the suspension wire 2222, it is possible to avoid the lens barrel 130 from colliding with the suspension wire 2222 during deformation, enhance the durability of the suspension wire 2222, make the combined structure of the suspension wire 2222 and the support frame 120 more compact, and contribute to realizing the miniaturization design needs of the lens module 10.

[0040] Furthermore, as shown in FIGS. 5, 6, and 8, a first relief groove 131 is formed in the lens barrel 130. The first relief groove 131 is provided on the side facing the flexible structure 2221 of the lens barrel 130, and at least a part of the orthographic projection of the flexible structure 2221 on the lens barrel 130 overlaps with the first relief groove 131.

[0041] In this embodiment, by arranging the first relief groove 131 and the flexible structure 2221 to cooperate with each other in the lens barrel 130, when the lens barrel 130 moves relative to the support frame 120 and deformation occurs, the first relief groove 131 allows the first flexible arm 22213 to retract, avoiding collision between the lens barrel 130 and the shake correction reset member 222, enhancing the durability of the shake correction reset member 222, and making the structure between the shake correction reset member 222 and the support frame 120 more compact.

[0042] As shown in FIGS. 5 and 7, in one embodiment, the support frame 120 further includes a cover plate 123. The cover plate 123 is detachably connected to the frame body 121 and is provided to cover the upper side of the shake correction reset member 222.

[0043] When assembling the lens module 10 of this embodiment, first, the shake correction reset members 222 are respectively connected to the frame body 121 and the lens barrel 130. Then, the cover plate 123 is provided to cover the upper side of the frame body 121 to seal the opening of the movable cavity 1211. The cover plate 123 is provided with a light passing hole corresponding to the lens barrel 130. Thereby, after connecting the cover plate 123 and the frame body 121, the cover plate 123 and the lens barrel 130 are installed at a distance from each other. The cover plate 123 blocks dust, impurities, etc. in the external environment, protects the lens barrel 130 and the shake correction component 220 inside the movable cavity 1211, and can enhance the durability of the lens module 10.

[0044] Specifically, as shown in FIGS. 3, 7, and 8, the focus reset member 232 is provided on the side away from the hand shake correction reset member 222 of the support frame 120. The focus reset member 232 includes a second fixing portion 2321, a second flexible arm 2323, and a second connection portion 2322. The second flexible arms 2323 are respectively connected to the second fixing portion 2321 and the second connection portion 2322. The second fixing portion 2321 is connected to the base structure 110, and the second connection portion 2322 is connected to the support frame 120.

[0045] In this embodiment, by installing the focus reset member 232 to be connected to the support frame 120 and the base structure 110 respectively, when the support frame 120 moves relative to the base structure 110, the focus reset member 232 can provide an elastic force for resetting the support frame 120 to the support frame 120, and an electrical connection effect can also be realized by the focus reset member 232 between the base structure 110 and the support frame 120. When the focus reset member 232 deforms, the second flexible arm 2323 deforms to store elastic potential energy, and finally drives the second fixing portion 2321 to reset and move relative to the second connection portion 2322 to reset the support frame 120. The second fixing portion 2321 is electrically connected to the base insert 112 of the base structure 110, and the second connection portion 2322 is electrically connected to the frame insert 122 of the support frame 120.

[0046] Furthermore, as shown in FIG. 7, a second escape groove 133 is formed in the lens barrel 130. The second escape groove 133 is provided on the side of the lens barrel 130 facing the focus reset member 232, and at least a part of the orthographic projection of the focus reset member 232 on the lens barrel 130 overlaps with the second escape groove 133.

[0047] Thus, when the lens barrel 130 moves relative to the base structure 110 and deformation occurs, in order to prevent the lens barrel 130 from colliding with the focus reset member 232, the second escape groove 133 can retract the second flexible arm 2323, enhancing the durability of the focus reset member 232 and making the structure between the focus reset member 232 and the lens barrel 130 more compact. Specifically, the number of focus reset members 232 may be two, three, four, or four or more. A plurality of focus reset members 232 are uniformly arranged along the circumferential direction of the support frame 120. By installing the plurality of focus reset members 232 to be connected to the support frame 120, the anti-shake effect and reset stability of the focus component 230 can be improved.

[0048] Specifically, as shown in FIGS. 4 and 5, the focus component 230 further includes at least one set of guide structures 233. The guide structures 233 are movably connected to the base structure 110 and the support frame 120 respectively, and are used to drive the support frame 120 to move along a direction parallel to the optical axis L of the lens barrel 130.

[0049] In this embodiment, by installing the guide structures 233 to cooperate with the base structure 110 and the support frame 120 respectively, when the focus component 230 drives the movement of the support frame 120 to perform focus adjustment, the guide structures 233 limit the movement of the support frame 120 relative to the base structure 110, ensuring that the support frame 120 moves in a direction parallel to the optical axis L of the lens barrel 130, avoiding the deviation of the support frame 120 relative to the base structure 110, and improving the focus accuracy of the focus component 230.

[0050] Specifically, as shown in FIGS. 4, 6, and 7, a first guide groove 1112 is formed in the base structure 110, a second guide groove 1212 is formed in the support frame 120, the guide structure 233 includes a guide member 2331 and a stopper portion 2332, the guide member 2331 is movably provided between the first guide groove 1112 and the second guide groove 1212, and the stopper portion 2332 is provided at the opening of the first guide groove 1112 or the second guide groove 1212 along the movement path of the guide member 2331.

[0051] In this embodiment, the extending directions of the first guide groove 1112 and the second guide groove 1212 are parallel to the optical axis L. Thus, by the cooperation of the first guide groove 1112 and the second guide groove 1212 with the guide member 2331, the movement of the guide member 2331 can be guided, and the function of limiting the movement of the support frame 120 can be realized. At the same time, by providing the stopper portion 2332 at the opening of the first guide groove 1112 or the second guide groove 1212 to limit the movement of the guide member 2331, the guide member 2331 can be prevented from escaping from the first guide groove 1112 and the second guide groove 1212. The stopper portion 2332 may be connected to the base body 111 or the frame body 121, which is not limited herein.

[0052] In one embodiment, the guide member 2331 includes balls, and the balls cooperate with each other to roll in the first guide groove 1112 and the second guide groove 1212, respectively.

[0053] Thus, when the support frame 120 moves relative to the base structure 110, the balls slide relative to the first guide groove 1112 and the second guide groove 1212, ensuring that the support frame 120 moves relative to the base structure 110 along a direction parallel to the optical axis L. In a preferred embodiment, the number of balls is plural, and the plural balls are sequentially arranged along a direction parallel to the optical axis L and are accommodated between the first guide groove 1112 and the second guide groove 1212. Specifically, the first guide groove 1112 and the second guide groove 1212 may be V-shaped grooves, arc surface grooves, etc., which are not limited herein.

[0054] In other embodiments, the guide member 2331 may be a roller, the central axis of the ball is perpendicular to the optical axis L, and parallel to the bottom surface of the base structure 110. In this case, it is necessary to limit the axial movement of the guide member 2331 by the first guide groove 1112 and the second guide groove 1212. In a preferred embodiment, the number of the guide structures 233 may be multiple sets, and multiple sets of guide structures 233 are respectively connected to the base structure 110 and the support frame 120, whereby the guide stability and accuracy of the guide structure 233 can be improved.

[0055] Specifically, as shown in FIG. 3, the focus component 230 further includes a yoke 234, the yoke 234 is connected to the base structure 110, and the yoke 234 is magnetically adsorbed by the magnet steel component 210 to drive the support frame 120 and the base structure 110 to abut against both opposite sides of the guide structure 233.

[0056] In this embodiment, by installing the yoke 234 to cooperate with the magnet steel component 210, the yoke 234 can be magnetically adsorbed by the magnet steel component 210 so that the support frame 120 abuts against the guide structure 233 and presses the guide structure 233 against the base structure 110.
